Deliver tailored technical presentations, architectural diagrams, and demonstrations addressing performance, security, and reliability challenges. Address complex technical objections, security compliance questions, and edge-case architectural requirements. Take accountability for suitable solution deployment strategy as an integral part of all proposals.
Customer Adoption & Value Realization: Provide oversight to technical onboarding and implementation (not executing implementation), serving as the primary executive and engineering contact. Design structured migration and onboarding blueprints tailored to customer environments (DNS migrations, Zero Trust rollouts, WAF tuning). Act as lead consultant for customer engineering teams. Partner with Account Executives on discovery, demos, onboarding, technical health, risk, and expansion strategy. Proactively monitor customer health scores and telemetry to ensure rapid time-to-value and reduce deployment risk.

Provide thought partnership on architecture, AI control layers, security posture, and deployment confidence. Identify deployment risks early and provide remediation strategies.
AI Orchestration & Workflow Automation: Leverage AI agents, Large Language Models, and internal platforms to automate routine tasks such as RFP/Security Questionnaire responses, sandbox provisioning, telemetry monitoring, and documentation, reclaiming time for strategic customer advisory.
Education & Enablement: Partner with Enablement Team to design, build, and govern technical resources. Define, document, and educate internal teams and customers on SOPs, architectural best practices, and technical guides.
